Please look at the attached problem 5-20:
Determine the reactions at the points A and B of the frame.
I know that the following must hold true:
Sum(Moments(b)) = 0
Sum(Fx) = 0
Sum(Fy) = 0
No moment is indicated in the problem, so I'm not sure if that's needed. Your help is appreciated.© BrainMass Inc. brainmass.com March 4, 2021, 6:10 pm ad1c9bdddf
